Need help with a Honeywell HRDP16D1000X rev b

[aidycox 0]

Hi all I have bought this dvr to replace my pc based unit I have at work, I bought it from a guy on ebay and collected from his house, I know the unit isn't stolen or in anyway dodgy. I have the serial numbers and the unit is untouched

When I bought it I knew I would need passwords for it as the guy didn't know what they were

I got the dvr running but can only view cameras

Can someone help me with either a factory reset with this unit or default passwords

Regards Adrian

Ps I have not yet tried to remove the backup battery just incase it looses bios or something
